Specification forming part of Letters Patent No. 35.901, dated J nly 15,1862.

To all whom it may concern:

Be it`,known that I, J oHN W. STREET, of Salem, in the county ofColumbiana and State of Obie; have invented certain new and usefulImprovements in Machines for Harvesting Grain and Grass; and I do herebydeclare the following to'be'fa full and exact description of the same,reference-being had to the accompanying drawings, making part of thisspecification, in whicli'- f Figure 1 is a plan of my improved machine,partly in section. Fig. 2 is a side elevation of the same. Fig. 3 is aninside view of the 'ratchet-box, hereinafter described. Fig. 4 is afragmentary perspective view of the connection between the pitman andcutter-bar.

Similar letters of reference 'indicate correl Aspondiugparts in theseveral figures.

The nature ofthe invention consists, rst, in an improved' constructionof ratchet for connecting or disconnecting the'wheels with thedriving-shaft second, in an improved manner of constructing and mountingthe intermediate gear-wheels by which motion is communicated from thedriving-,shaft to the cutting 'apparatus; third, in an improved4construction of, drag-frame; fourth, in an improved manner of hingingthe nger-bar to the drag-frame.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A is the main frame, formed with houndse for the attachment of thetongue, andwith rigid hollow stud-shafts a a, upon which the carry'- ingand driving wheels B B turn.

C is a shatt'extending from side to side' of the frame A, completelythrough the; studshafts a a, and provided at each end with a box, D D',which may be of equal 'diameter with the hubs ofthe wheels B B and serveto retain them on'their journals. One or both of the boxes D D"1nay beprovided withpivoted pawls d d, which, when motion is -tobe com-`municated to the cutting apparatus, are held in or out of gear withratchet-teeth b on the face of the wheel-hub by means of an elasticlever, E, fulcrumed upon the shaft C and projecting on each side of theboxD through slots therein of suicient lengthto admit of turning thesaid lever, so that `it shall bear against either end desired of thepawls. By setting the lever so as to bear against the hooked or toothedends ofthe pawls the` latterwill takel firmly into the 'teethon thewheel-hub, and

thereby the motion of the wheel will be communicated through the pawlsdand box D to the'shait C. `By turning the lever vE so as to. bear4against the rea-r. ends of the p aWls d thel latter will be held out ofcontact with the teeth upon the wheel B, andthe latter will then be.free to turn without operating the cuttinglap I paratus. When the motionof the wheel is re'- versed, the elasticity ofthe leverEpermits the#pawls to slip over the teeth b, so that no mo= tion is imparted to thecutter.

F is a gearwheel keyed' upon ,the shaft C w and meshing with a pinion,G, which is' s ecured upon a sleeve, g. 1

y G is a bevel-gear, which is also secured upon the sleeve g. -The saidsleeve turns freely upon a secondary shaft, H, journaled transverselyvinthe -forward part of the main frame,

is ina/de, in such'positions that their forward` endsl will be embeddedin lthe eye I', the rear end of the rod J in theangle of the L, andthatofthe rod J at the outer end of the transverse arm, so that the rod Jshall constitute one of two parallel sides of the frame, and the rodJ adiagonal' brace.. The. flange I, projecting .l

downward from the outer rear corner'of the drag-frame, may eitherrestdirectly upon the ground, or maybe supported upon ashe of any suitableconstruction.'

K is the ii-nger-bar, secured by a N is the reciprocating cutter. y

'A O'is a shaft running in baarings o o on the drag-frame, and havingsecured to its yupper end a bevel-pinion, P, which meshes-with thebevel-gear wheel G.,- The lower end of the shaft O carries acrank-wheel, Q, which imparts a reciprocating motinito the pitman orconnecting-rod R, and thus Vto the cutter-bar. rI.heconnecting-rod isattached' tothe cutter y horizontal hinge, Z, to a plate, L', whichplate is attached' by a diagonal hinge, l', to thefouter face of the thebar is shown in redinFi'g. 2:; j S is the drivers seat.-
